China Silver Dollar 1934 - Genuine Or Fake ?

What is the diameter and thickness?
It does look well made, no different than some of my fakes.
And I have 10 like yours with none being genuine.
Also looks like it has been whizzed.
Not natural. I may go out on a limb and say the eye shape looks like the 1935 coin instead of the 1934, but I'm not so good when it comes to member provided pictures alone. There are too many cases where a genuine and fake are hard to tell apart for me to say. So apart from the weight, what are the other measures?

A genuine coin is 39.5mm dia and 2.5mm thickness meaning yours is smaller and thinner but yet the correct weight.
I doubt if it turns out to be legitimate .880 fine silver, but it does look nice even though the surface looks like somebody tried to shine it up.
I have 10 of these because I get them from various sources and then apply observations & measures to document Chinese fakes then add the data with photos in binders.
There are a couple binders of fake Chinese Dollars as well as a handful of duplicates in the boxes.
Just in case this is a doctored ringer, I'd be surprised. It's not easy to say sometimes if a coin is genuine or not based on the provided pictures alone.
It's my hobby.
I was fooled into buying a Chinese dollar some years ago because I believed the seller didn't know what he had. After I got it it proved to be not genuine and I was duped by my own greed. After that I became interested in acquiring many of these Chinese fakes for study. I bought some good lab equipment to aid that study. Since I'm retired I have the time and enjoy this part of my hobbies.

Very hard to tell, faking technology has gotten so sophisticated nowadays.
